Why does my wall thump whenever the upstairs shower, sink or toilet is used?
Our answer
Water hammer from sudden water-flow changes or a loose pipe can thump through walls; ask a plumber to check pressure and pipe restraints.
Why this approach makes sense
Materials, cleaning instructions and equipment design vary. Pick a reversible approach that fits the exact surface or appliance.
Before you try it
